Peace of Bautzen ends German-Polish war

1018

Boleslaw the Brave of Poland and Henry II of Germany finally ended fifteen years of bitter border fighting. Poland kept Lusatia and Milsko. Within weeks Boleslaw marched east and captured Kiev, briefly installing his son-in-law on the Rus throne in an extraordinary display of Piast power. The peace acknowledged Poland as a force that the Empire could no longer afford to ignore.
